Narrowband auscultatory blood pressure measurement
2002
IEEE Transactions on Biomedical Engineering
Auscultatory blood pressure measurement uses the presence and absence of acoustic pulses generated by an artery (i.e., Korotkoff sound), detected with a stethoscope or a sensitive microphone, to noninvasively ...
The acoustic noise, on the other hand, appears in both microphones simultaneously. ...

Application of the PE method to up‐slope sound propagation
1995
Journal of the Acoustical Society of America
The control mn is used to estimate the ambient noise processes on long-term scales. Maps of the anthropogenic signal to the ambient noise ratio of the climate system can then be constructed. ...
Use of simplified coupled mode propagation for the prediction of impulse responses of megameter trans-Arctic propagation paths. Herbert A. Freese (Sci. Applic. Int. ...
This ratio is only 20 (between 0.5 and 10 cm 2) for the "compact" versus "diffuse" axis (from/a/to/i/). ...

Effects of errorless learning on the acquisition of velopharyngeal movement control
2012
Journal of the Acoustical Society of America
In that respect, several alternatives are discussed to represent the Herglotz density as a sum of a finite number of basis functions. ...
In practical cases only a limited amount of information is available to compute the Herglotz kernel, typically because a finite number of sensors is used for the measurement. ...
The LCMV deals with the more general case of multiple desired speakers. It is argued that the MVDR beamformer exhibits a tradeoff between the amount of speech dereverberation and noise reduction. ...

This may also result in reduced sensitivity to the temporal fine structure of sounds. ...
In extreme cases, the IHCs/synapses/neurons may be almost completely non-functional over a certain region of the cochlea, giving a "dead region". ...
To optimally benefit from binaural unmasking and to preserve the spatial impression, several extensions for the binaural MVDR beamformer and MWF have been recently proposed, which aim to also preserve ...
